I got the following message when opening netbeans that jdk has not been found on this computer. I have got the jdk installed, and set the bin directory in the environment. Btw, I am using Windows 10 pro 64 bit.
I have tried this in the command prompt.
C:\Users\admin\Downloads>netbeans-8.2-windows.exe --javahome "C:\Program Files (x86)\Java\jdk-10.0.2"
but then i get this message.
It's only the launcher stub.
OS: x64
Does someane know what i can do about this?
Thanks.
Java 8 is still the standard for now. Uninstall java 10 and install this and reset your env vars.

Your computer is 64bit. so your jdk should be in Program Files not Program Files(x86)
C:\Users\admin\Downloads>netbeans-8.2-windows.exe -javahome "C:\Program Files\Java\jdk-10.0.2"
JDK 8 was the latest version at time of NetBeans 8.2 is developed. For that reason, JDK 8 is required for installing and running all NetBeans Bundles of version 8.0 - 8.02. They do not run on JDK 9 or later.
Download JDK 8
Download latest version of NetBeans

I am setting up a new machine after a long time.
I installed java using home brew:
brew install openjdk
In my .zshrc file I added:
export PATH="/usr/local/opt/openjdk/bin:$PATH"
Running 'java -version' gives the following output:
openjdk version "18.0.1.1" 2022-04-22 OpenJDK Runtime Environment
Homebrew (build 18.0.1.1+0) OpenJDK 64-Bit Server VM Homebrew (build
18.0.1.1+0, mixed mode, sharing)
When I try to run the netbeans 13 installer pkg, I get the following message:
No Java Found NetBeans IDE cannot be installed. This software can be
installed with Java 8 or newer. Please download and install the latest
update of Java 8 from
http://www.oracle.com/technetwork/java/javase/downloads/index.html and
restart NetBeans installation.
I figured maybe I need to set the java home variable. But not sure where the correct location is. I tried:
export JAVA_HOME=/usr/local/Cellar/openjdk/18.0.1.1/libexec/openjdk.jdk/Contents/Home
But the error is still there.
Have I set my JAVA_HOME variable correctly ? How can I make sure that I have set the correct location ?
How can I get the Netbeans installer to install ? Why does it not see the JDK ?
EDIT:
If I run the following command:
/usr/libexec/java_home
Then I get the output:
The operation couldn’t be completed. Unable to locate a Java Runtime.
Please visit http://www.java.com for information on installing Java.
This is because I installed java via homebrew and did not see this message output in the end:
For the system Java wrappers to find this JDK, symlink it with sudo
ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk
/Library/Java/JavaVirtualMachines/openjdk.jdk
Run the command above to create the symlink, then netbeans installation proceeds. Wasn't necessary to set path or home. Set cpp flags because cpp is cool.
Even for other versions such as 11 it may be necessary to run a similar command. Homebrew mentions it, but unless you’re paying attention may not notice it at the end of the installation.
I suspect the problem is that the NetBeans 13 installer does not support the use of JDK 18, because NetBeans 13 itself does not officially support JDK 18. From the Release Notes (with my emphasis added):
The Apache NetBeans 13 binary releases require JDK 11+, and officially
support running on JDK 11 and JDK 17.
Also, note that:
NetBeans 13 was released on March 4, 2022.
JDK 18 was released 18 days later, on March 22, 2022.
So while NetBeans 13 may appear to run fine with JDK 18, it seems probable that the installer does not support the use of JDK 18, which didn't even exist when the installer was released. Unfortunately the installer is providing a very poor error message when you attempt that:
No Java Found NetBeans IDE cannot be installed. This software can be
installed with Java 8 or newer. Please download and install the latest
update of Java 8 from
http://www.oracle.com/technetwork/java/javase/downloads/index.html and
restart NetBeans installation.
The installer's error message is highly misleading for two reasons:
Instead of "No Java Found" it would be more accurate if the error was "No supported version of Java found".
The advice "Please download and install the latest update of Java 8" makes no sense because NetBeans 13 doesn't even support the use of JDK 8.
So this looks like an issue with the NetBeans Installer rather than NetBeans or Java 18. You have a couple of workarounds:
Run the installer using JDK 17 instead of JDK 18. Once you have NetBeans installed and running on JDK 17, you can then add JDK 18 as a second Java Platform, or edit netbeans.conf so that NetBeans will use JDK 18 instead of JDK 17 after a restart.
Don't use the installer at all. Instead, just download the zip of NetBeans named netbeans-13-bin.zip, unzip it, and then edit netbeans.conf so that NetBeans will use JDK 18.
I'm trying to install NetBeans on macOS Mojave - I want to work with the Matisse GUI builder.
I installed Open JDK 12 via SDKMan. Then I ran this installation script, which the Apache NetBeans docs refer to.
However, after installation NetBeans didn't start. I downgraded to Open JDK 11 via SDKMan, but it also didn't work.
Any ideas how to debug the problem? Anyone used NetBeans with a recent JDK version (10+) on MacOS?
I am trying to install Netbeans but it gives me this error:
The is no JRE at the location C:\Program Files\Java\jdk11.0.2
I have tried specifying --javahome argument to the installer but still nothing and it is installed as you can see in the snippet attached.
Thanks!!
Netbeans 8 does only support java 8, better upgrade to Netbeans 10 which works with Java 11.
I got this error message when trying to install NetBeans 8.2 in Windows 10 64-bit.
Java SE Development Kit (JDK) was not found on this computer
I installed the JDK, and set the bin directory in the environment.
I had the same problem when I first tried to install Netbeans 8.2. I had JDK 11 installed and I tried everything but was not successful. The problem was with Netbeans 8.2 as it does not support JDK above 9. So I installed JDK 8 and it solved the problem for me. You should try this.
Currently, I am running Mint Linux (Release 9). I need to downgrade Java from version 1.6 to 1.5, and have been trying to figure out how to go about this. So far, I've had no luck. The package manager doesn't seem to have it.
Does anyone have any suggestions?
Thanks,

As you explained in your comments, you need JDK 5 because you are working on the source code of Android itself and the instructions say:
Ubuntu Linux (64-bit x86)
... JDK 5.0, update 12 or higher.Java 6 is not supported, because of incompatibilities with #Override.
You can do this:
Uninstall any Java that you got via the package system of your Linux distro
Download JDK 5 Update 22 for Linux
Run the JDK installer with sudo, install it wherever you like (for example in /opt or /usr/local)
Set your PATH environment variable to include the bin directory of the JDK
There should be no need to downgrade your Java installation to develop for Java 1.5. If you are using a tool such as Eclipse, you can set the project attributes so that it tests for Java 1.5 compatibility, and gives errors if you use a Java 6 feature. If you absolutely insist on having a Java 1.5 JDK then just install it alongside the default installation and use it in place of Java 1.6.
This should be a question for SuperUser.com, but my recommendation is to download the 1.5 JDK, and change Java path to where you downloaded it.
Or you could use the info on Ubuntu Help, it should work for you since Mint is based on Ubuntu. That link explains how to select the version of Java.
